A phase-change energy-storage material, silicone rubber (SR) coated n-octadecane/poly (styrene-methyl methacrylate) (SR/OD/P(St-MMA)) microcapsule composites, was prepared by mixing SR and OD/P(StMMA) microcapsules. The microcapsule content and silicone rubber coated method were investigated. The morphology and thermal properties of the composites were characterized by scanning electron microscopy (SEM), thermogravimetric analysis (TG), differential scanning calorimetry (DSC) and heat storage properties. The results showed that the thermal and mechanical properties of SR/OD/P(StMMA) composites were excellent when the microcapsules were coated with room temperature vulcanized silicone rubber (RTVSR),of which content was 2 phr (per hundred rubber). The enthalpy value of the composites was 67.6 J g(-1) and the composites were found to have good energy storage function.
